Abstract
The utility model relates to a double-spider cardan joint, which comprises a flanged yoke, spiders and bearings, wherein the two forks of the flanged yoke are connected together by a Philip's head screw and a nut, that is, the flanged yoke, the bearings, the Philip's head screw and the nut are connected together to form a closed yoke, a floating clearance B is arranged between the spider and the bearing, both ends of the Philip's head screw are provided with a planar bearing and a laminated spring, the hollow C of the spider only accounts for 7 to 8 percent of the cross section of the spider, a peristaltic lubricating system is arranged in the hollow C of the spider, and a sealing part is arranged in a clearance D next to the bearing. Compared with the prior art, the overall driving capability of the cardan joint is enhanced by 28 to 30 percent; the floating spider without a drifting clearance can be automatically balanced at the central point O of the structure, so that the additional stress produced by additional moment is reduced, and therefore the cardan joint is particularly suitable for high-speed driving; the driving of the whole cardan joint is stable, and the service life is long.
Description
Technical field
The utility model relates to a kind of Hooke's joint.
Background technique
Hooke's joint is made up of two flange jaws, a cross axle, four bearings and some other part usually.Hooke's joint shown in Fig. 1 (b) is the typical structure of the whole jaw Hooke's joint of China, they by the flange jaw 1., cross axle 2., bearing 3., the pad of adjusting axial clearance 4., rigid bearing 3. the snap ring of usefulness 5. wait and form.The Hooke's joint of this structure has following shortcoming: the solid of rotation outer rim space A that 5. (1) snap ring accounts for more, and it is very big that the driving torque ability is reduced influence; Preset clearance and service wear when (2) pad is 4. owing to installation make cross axle 2. produce skew and impact especially inapplicable high speed transmission at center O point.Owing to there is above-mentioned shortcoming, the transmission capacity of whole Hooke's joint can not be improved, the transmission balance is poor, and working life is not long, more the transmission of incompatibility high speed.
Once open " a kind of Hooke's joint " (China of Chinese patent, publication number CN2743603, open day on November 30th, 2005), form by cross axle, bearing housing, thrust washer, needle roller and seal ring and dust-proof cover, dust-proof cover is arranged on the cage openings end, the spindle nose of cross axle is close in the dust-proof cover inboard, and top, the outside is provided with snap ring, and snap ring is stuck in the annular groove of inboard, cage openings end.Because it adopts snap ring, has above-mentioned shortcoming equally.
The model utility content
The purpose of this utility model is to overcome the above-mentioned shortcoming that prior art exists, and a kind of double universal joint pin cardan joint is provided.It compared with prior art, the whole 28%-30% that improves of transmission capacity; Existing float and the cross axle that do not have a moving gap of string can reduce the additional stress that additional moment produces in architecture central point O autobalance is specially adapted to the high speed transmission; Whole universal joint stable drive, long service life.
For achieving the above object, the solution that the utility model is taked is: a kind of double universal joint pin cardan joint, comprise the flange jaw, cross axle, bearing, cross screw rod and nut are coupled to one to two forks of flange jaw, it is the flange jaw, bearing, cross screw rod and nut are coupled to one, form the jaw of sealing, flying height B is arranged between cross axle and the bearing, cross screw rod two ends are provided with plane bearing and folded spring, the middle vacancy C of cross axle only accounts for the cross section 7%-8% of cross axle, be provided with the wriggling lubrication system among the middle vacancy C of cross axle, be provided with Sealing among the gap D of adjacent bearing.
This Hooke's joint compared with prior art has following characteristics:
(1) with the snap ring in cross screw rod and the nut replacement conventional construction, made full use of the outer rim space (reaching 98%-99%) of solid of rotation, bearing is increased, bearing and cross axle area of contact increase, and therefore can improve transmission capacity about 25%.And the middle vacancy C of cross axle only accounts for the cross section 7%-8% of cross axle, because middle vacancy C can heat-treat, the raising of cross axle performance surpasses its cross section and reduces the performance reduction that brings, and helps making full use of the intensity of material on the contrary.
(2) flying height B (size of flying height B is decided according to design) is arranged between cross axle and the bearing, this flying height B does not have the moving possibility of string.Because of cross screw rod two ends are provided with plane bearing and folded spring, the middle point floating that makes cross axle reaches autobalance on structure centre point O, and is effective especially when high speed rotating.
(3) utilize cross screw rod and nut that two forks of flange jaw are coupled to one, promptly flange jaw, bearing, cross screw rod and nut are coupled to one, form the jaw of sealing, and its structural strength improves greatly.And cross axle only floats in structure, existing float and do not have the moving gap of string.
(4) utilize the gap D of the middle vacancy C of unnecessary space such as cross axle and adjacent bearing to be respectively equipped with the wriggling lubrication system and than effective seal part (as band skeleton lips TC type Sealing).
This Hooke's joint compared with prior art, the whole 28%-30% that improves of transmission capacity.Existing float and the cross axle that do not have a moving gap of string can reduce the additional stress that additional moment produces in architecture central point O autobalance is specially adapted to the high speed transmission.Whole universal joint stable drive, long service life.
